A process for alkylating hydroxyaromatic compounds with a terminally unsaturated polymer in the presence of a partially or completely dehydrated heteropoly catalyst. The alkylated hydroxyaromatic compounds so formed are useful as percursors for the production of fuel and lubricant additives.
L'invention concerne un procédé d'alkylation de composés hydroxyaromatiques avec un polymère de terminaison insaturé, en présence d'un catalyseur hétéropoly partiellement ou complètement déshydratté. Les composés hydroxyaromatiques alkylés ainsi obtenus sont utilisés comme précurseurs dans la production d'additifs pour combustibles et lubrifiants.
